ICE-CAN COVER.

Specification of Letters Patent.

Application filed May 19, 1916. Serial No. 98,531.

the purpose of catching and holding the sediment present in the raw water from which the ice 1s manufactured.

In the manufacture of me raw water is placed in cans which in turn are placed in refrigerating or freezing tanks. The water in these cans begins to freeze at the outer sides against the walls thereof. Usually means is provided for sending a blast of air through the water to agitate the same and cause movement thereof against the inner surface of the ice as it is formed, which prevents the settling of the sediment in the water against these sides and consequently prevents thefreezing of the same within the ice as it' is formed. The air flowing upwardly through the water not only agitates the same but causes an upward movement of the sedimenttherein toward the top of the water in the can.

One object of my invention is to provide a cover having means to permit the water to pass therethrough and also having means which is adapted to receivean overflow of water and retain the sediment therein and is also provided with means whereby the water may flow out of the said sediment retaining means back into the body of water within the can. As a result of such arrangement I have been able to bring about a great econ- ,omy in the cost of manufacture.

A further object of my invention is to provide a cover which may be'more cheaply and economically.constructed than other covers of which I am awareand thereby decrease the manufacturing cost of the same. It will be seen therefore that my invention accomplishes an econom not only in the matter of the cost of manu acture of the cover itself, but also in the cost of'production of ice in that it decreases the amount of waste water resulting fromits use. p p p In order that my invention maybe more readily u erstood and its pract cal edvane tages more fully appreciated, reference should be had to the accompanying drawing in which I have illustrated certain forms of convenient embodiments thereof. It will be understood however that changes in the details of construction may be made within the scope of my claims without departing from my invention.

. In the drawing,-+

. Figure 1 is a vertical central longitudinal sectional view of a can containing water and provided with a cover embodying my invention.

Fig. 2 is a similar view with the water in the can partially frozen.

Fig. 3 is a top plan view of a cover embodying my invention. I

Fig. 4 is a transverse sectional view taken on the line l4 of Fig. 3; and

Fig. 5 is a top plan view of a can and a cover, the latter showing a modified construction embodying my invention.

Referring to the drawing, 1 designates a can and a Patented J uly 1?, I917.

can the side wallsof which are slightly flared upon the top edges of the walls of the can.

The base 5 of the cover should fit loosely within the upper portion of the can as shown.

The said base is provided with a recep tacle 8 upon its upper side formed by means of the flange-like outwardly flaring walls, as shown. The lower edges of said walls are provided with lateral flanges 9 which are riveted to the base 5. It will be imderstood thatthe flaring flange like walls may be otherwise secured to the base 5, as by soldering. The said base 5 is provided with an opening 10 which extends transversely thereof and which may be situated, as shown in Figs. 1 to 4 inclusive at one end portion of the receptacle 8.

A flange 11 situated at or adj acentto the inner edge of the opening 10 extends transversely of the receptacle 8 and isof a height considerably less than that of the walls of said receptacle 8, as is clearly shown in the drawing. The opposite ends of the flange 11 are square, that is to say, they are straight so that between the said ends and the adjacent side walls of the said receptacle there are spaces terminating at their lower ends in acute angles 15 as best shown in Fig. 4 of the drawing. It will be seen that between the flange 11 and the side walls and one end wall of the receptacle 8, a chamber is'formed into which the water is discharged as it pours over the top edge of the flange 11;

In Fig. 5 of the drawings the construction is identical with that shown in the preceding figures, except that the opening 10 is situatc'd practically at the center of the'receptaole 8 and that there are two flanges 11*, one

at each side of the opening 10 so that the water which passes up through the opening 1O is discharged in opposite directions over the top edges of both flanges 11".

In operation the cans are supplied with raw water, being filled to a point such that when the covers are placed in position therein the bases thereof will occupy positions a half-inch, more or less, above the top" surface of the water. As the water freezes it expands, the expansion being 'sufficient'to bring the top of the ice which is formed into contact with the said base. As already stated, the water first begins to freeze at its outer side or surface. The passage of the blast of air through the water agitates it to cause movement of the water against the inside surfaces of the ice as it is formed, thus preventing lodgment of sediment and objectionable foreign matters upon. the said walls. As the ice continues to form the top surface of the water rises until it also contacts with the base 5 of said cover and passes upwardly through the opening 10 or 10 and owing to the passage upwardly through the water of the blast of air as described, the water is caused to splash or flow over the top edge of the flange 11 or the top edges of the flanges 11*, as the case may be. The sediment which passes over the top of the said flange or the tops of said flanges, as the case may be, is retained in the chamber between the said flange or flanges and the opposing end or ends of the receptacle, buta portion, more or less, of the water thus caused to overflow returns around the opposite edges of the flange 11 or flanges 11 to the body of water in the can. It follows that when the body of water in a can is frozen only a very smallproportion thereof has lodged in the chamberof said receptacle. 8, but all or substantially all of the sediment will have found lod'gment therein.

I claim ,I
